slidable along but feathered to the flange B8.

Surrounding the clutch B7 is the brake drum, generally indicated as @having the cylindrical flange C1 with the clutch rings 'C2 .feathered thereto, and interposed betiv'een the clutch rings BQ. The druInC has secured to it the generally cylindrical sleeve C4, in the outer end of which is secured vthe `shaft C5 which carries the bevel pinionC in mesh With the bevel gear C7. CS generally indicates any suitableball or roller bearings for the sleeve C4'.

Surrounding and spaced from the shaft B is the generally cylindrical sleeve D, rtatably mounted in the ball bearings generally indicated as D1. The sleeve .D is provided with an outwardly projecting flange D2, connected by any suitable disc kor spidermember .D3 with the cylindrical flange C1 of the clutch drum C.

Pi voted upon the member D3 are thefle'vers Screw threaded into the levers, intere `mediate their ends, are the pins E1,"Which pass through apertures E2 inthe member-D3,

and are fixed at their inner ends inthe collar E3 lying adjacent the clutch rings B and C2. The opposite end vof each of said .levers E, engages, as at Et, a collar E5, slidable along the exterior of the sleeve D.

ln order to insure the release of the collar E3 I may provide a plurality of )ins E10,

Elz'and provided with a headEls, between which and the outer face of 'D3 is compressed the helicalspring EM,` E vis any suitable inner abutment for such spring adapted to engage the member D3 and to bridge the apertures therein. n

The slide collar E5 is circumferentially grooved asat Eto 4receive the open ring 4or `Ushaped `member G, provided with the H4 the innerend of which is opposed to the sleeve H2, the opposing portions" being so shaped as to permit a slight movement of the crank H3 in relation to the shaft G? before the paivl member Hengagesthe" sleeve `each passing through the member,` 3 als at H2 and prevents further relative movement of crank and shaft. Surrounding the drum C is the brake hand l, upstanding :troni one end ot which is the S abutment men'iher l" adapted to engage an adjustable stop member K2 shown as screw threaded in the boss l@ which projects inwardly i'rom the hmrsing rap or cover A1. The stop n'iomber K2 is outwardly headed as in at lit and is provided with a leek nut K, Mounted for movement in a hrev K project ing i'rom the side of the housing cover A1 is the piston K7, the reduced end KS ot which penetrates the upstanding;` brake band abut- 15 ment K2, the abutment l@ at the opposite end of the brake band. and the stop member K2 which is axially apertured to receive it and terms a guide therefor. lim is a helical spring adapted to be compressed between the 50 abutments K1 and li. The piston K2 is slotted to receive the link K12 pi voted to it as at K1 and pivoted at M at its opposite end to a link K the opposite end oitl which 1s pivoted as at Km to the adjustable stem 20 K12. K12 is a screw threaded adjustment sleeve provided with the head K2 and the lock nut K2". K21 is a lock nut, screw threaded at the outer end of the pin KU. o The mechanism for actuating,Y the clutch U0 and brake band are described as follows:

I is any suitable control shaft mounted for eXamplein the bearing;- sleeve Il which passes upwardly through the cover A1. I2

Q are any suitable lock nuts for locking the d sleeve I1 in position. l2 is any suitable crank or handle secured against rotation to the outer end ot the shaft l, and held in position7 tor example by the lock nuts I4. lt may be operated in any suitable manner, for

40 example by means ot the link P2 extending toany suitable control member or lever.

l is a flange on the shaft I to limit the out iard, movement oit the shaitt .l in relation r to the sleeve l1. Secured against rotation in 40 relation to the shaft I, and poiitioned at the lnner end thereof is the crank arm l2). I' provide ttor lateral adjustment ot the shattl l as tollows: l is a plate, slotted as at lu, r against which abut the lock nuts l2. The "0 sleeve Il is provided atl its inner end with the outwardly projecting collar or flange V'l.12. It will be understood that the plate l1 rs slidable along the housing, being` guided r tor example within the groove IM'. The d lOllSnt. itfell is .slotted as at l transversely of the inclined slot l1. The movement ot such plate alonesuch grroo ve and the engtg" ment between the inclined slot l, and the m sleeve l1 serves vto move such lsleeve along;` the slot 112, the lock nuts l2 being loosened to permit such movement and being; tightened when it is com pleted.

The crank arm l has pivoted to it the link L the op pesite end ot which is pivoted to the juncti( o :t the brake band control-- ling toggle links H22 Kw. The arm l also has pivoted to `it about the same axis a second link L1v the opposite end oit which is pivoted to a second toggle consisting,- ol' the links L2 and L2. The opposite end ot the link L2 is pivoted to a pin lit similar to the pin K and similarly adjustaiiile. 'lfhe link .if is pivoted at its outer end lo tho outer end of the clutch operating lever ll".

The lnovement of the toggle links 'H22 b' is limited by the stop L, so positioned that when the links Km and K25 are j iositionial ther aigainst 'the parts are in neutral with both the brake band and the clutch disengaged. The movementoif the toggle links L2 L2 in the opposite direction is limited by the stop L2. lllhen they are so positioned the brake band is rleased and the clutch is set. Then the links l. l 15 are in the po sition shown in tall lines in Figure 2 the brake is setand the clutch is released.

As shown in Figures (l, 7 and S the pivot bolt M which connects the links K12 lil i.: secured above by the nut M1 and has the head M2 below with its lower end rounced to ride upon the retainer block M4 which has the groove "d5 to receive the rounded head M2 when the levers K12 K25 are in line and the brake is set. The retainer block has the downwardly projecting pins lr guided in the bracket M7 bolted at MS M8 to the cover plate A2. lnterposed between the block MAl and the bracket M7 is a flat spring M2 which forces the block Mt upwardly against the stop pins M1". The block M4 is cut away on its upper side as at l\ u to allow clearance 'tor the nut M22 on the lower end of the shaft l.

The use and operation of my invention are as follows:

I employ a driving shattand a driven shalt with a clutch mechanism between them, whereby the driven shatt may be driven at will from the driving sha'ttu and ay brake, herein shown as includingT a drum applied to the driven shaft and a band thoreabmit. One application ot my clutch and brake niechanism is to hoistingl devices wherein intermittent hoisting and loading movements are desired, itor example the winding in or payingV out ot a cable. and wherein it is desirable to provide a brake tor the driven member, whereby it may be held positively against movement when not being` actually driven. l house the mechanism completely, there projecting 'trom the housing the end oit the sha'lt lY with its outer control lever l illithiii the housing` is enclosed not only the actual clutch and brake mechanismsv` but the actuating mechanisms therefor. l have indicated, as my preferred actuating' mechanisniis; toggle connections or pairs of toggle linl's, one ot each ot such pair of' links being' pivoted at its outer end to the housing, or to the adjustlill) Cil abile members KU, L4', positioned within the housing, and adjustable for example" by means of`t'l'1e'lo`cl`rinuts E201 This adjustment may be externally' affected so that in theinormal operation of thev device the housing need never be opened'.

To effect the actual brakingv and clutch operation I provide any suitable clutch mechanism, for example the mechanism earlier described in detail above.` The clutch, however, is controlled by the lever G2 on the shaft G3; and the shaft G3 is rotated in response t-o the crank arm 4H3, there being then toggle links L2 La between the crank armflrl3 and the adjustable member L4. The springs Itlfserve` to keep` the clutch discs normally disengaged, the springs E14 pressing against the heads E13 of the pins E10 and thus withd-awing the collar E3 from the' clutch' rings B and C2.

The b fake mechanismv is characterizeldv by a brake drum upon the driven shaft and a brake band K tliiereabout, the brake band being normallyvheld inoperative or disengagerl, for example' by the helical spring K10; Itwill thus be clear that I providea mechanism wherein` bot-lf clutch and( brake are normally disengaged and are yieldingly soaheld, but wherein a positive actuating connection -is interposed, herein shown as a toggle connection between the-surroundinu housing. A1 andthe clutch controlling cran f arm H? and the brake controlling piston K7 respectively, whereby, in response to actuation of' the respective toggle connections, either the clutch or the brake may be engaged, in opposition -to the yielding means normally tendingy to hold them disengaged. To actuate the toggles I provide the control shaft I with the -crank arm IG thereupon, and-links'LL1 between it and the respective toggle connections.

The parts are so proportioned that when the crank arm I'i ispositioned to the extreme right, as shown in Figure 4, both toggle connections are broken and both clutch i and brake are therefore yieldingly heldin inoperative` position. As the arm I6 is rotated to the left it first straightens the brake controlling toggle, and actuates the brake. At the Sametime the link fl operating upon the toggle' linksL2 and L3 moves the crank arm H3 and its pawl HcOunterclockwise whereby the pawl Hfengagesthe stop H? on the shaft`G3. As ther'otation of the arm I6 continues further the toggle connection for` the brake.- is broken and the brake isreleased, and the clutch connection, effected, through rotation of the shaft G andmovementofithe arm G1 is made.-

In the-form herein shown in Figures 2 and l when the link K12 abuts against the j stop K'both clutch and brake are necessarily inoperative or neutrali.V lVheny at the opposite end of the excursion of they arm I", the link L3 reaches the' abutment L the brake 'necessarily inoperative and the clutch operative. Obviously I might 'otherwise proportion `the' stop' L7: and provi-de for an additional neutral period atthe termination of the excursion of the leverlII y The` adjustment ofthe brake, either to take up wear, or to control the tightness or looseness of operation, may be efiectedffroni either Vside of the *housing and it may be necessary to effect the adjustment from both sides,` owing to the close' spacingof the brake members Kv and K in relation to 'the lugs K3 an'd"-K. ThereforeI provide, 'in addition to the stem -K17 the hollow bushing K2, shown as screw threadedv into the boss K3 which projects inwardly from the housing cap or cover A1. The bushing Kzmay be adjusted bymeans of the external lock nut KSL screw threaded upon the outer end thereof; y

The adjustment is effected by the longitudinal movement ofthe bushing K2, against .which abuts the brake band `abut-ment K10, shown for example in Figure 3'. j

The adjustable members L4 kand K2 and K17 permit of adjustment or take-upto provide-for wear ofthe various parts in connection with the means for actuating brake and clutch! I provide further an' adjustment of the shaft I in relation to the brake and clutch controlling the toggles, in order to-y adjust or control the relation between brake and clutch actuation. j Y V Under-some circumstances a brief time interval Vmay be. advantageous `between the4 re'- iease ofthe brake and the actuation of the clutch, andfor other purposes it may bedesirable toV have the cl'ut'chactuated theinstant the brake is released. timing I1 effect by the said adjustment inthe position of the shaft I.
